' In France October 15, 1935 6 ClaimsI. (01.221-103) The object of. the present invention is to provide means for measuring differentquantities of liquids'with one and the same apparatus in such a manner as to avoid all Waste of the liquid ;when it is necessary to fill a, receptacle having a volume which is less than the maximum volume of liquid in the measuring means, while another object of the invention is to enable the measuring device to be controlled, while it is in different positions, in a particularly simple and convenient manner.

A further object of theinvention j is to provide a filling, and measuring apparatus that can be constructed and assembled. simply and easily withoutrequiring exact and careful manufacture of its parts. I I

A measuring-filler which enables the foregoing objects to be realized possesses the features set forth'inthe following description and in the claims appended at the end of the said description.

r The preferred: form of the invention is illust'rated, by way of example, in the accompanying drawings wherein:

. Figs. 13-18 denote views similar to the two foregoing ones but with three different positions of the piston. I

Fig. 19 is a fragmentary perspective view showing differentpossible positions of the delivery tube. V I s The apparatus shown'in the accompanying drawings comprises a cylinder I of glass (Figs. 1 and 2), enclosed in a, metallic, perforated frame 2. This cylinderl is secured between'two endmembers3 and 4, which arescrewed to the frame 2, and sealing rings 5, 6 are inserted between these various elements to ensure that the cylinder is held tightly in place, while at the same time all risk of the glass cylinder I being broken is avoided.

Within the cylinder I is movable a piston I having packing grooves 8 to ensure tightness. The piston rod 9 is surrounded by a sleeve II] (Figs. 2-4) which engages frictionally on the rod 9 in such a manner as to allow these two members to rotate easily relatively to each other.

The sleeve III (Fig. 2) bears at its lower extremity on the piston I itself and at the other end against the handle I I by which the piston is operated. In this way the sleeve I9 always follows the piston 'I in its longitudinal movements.

The sleeve I6 is provided with longitudinal grooves I2 I2 I2 and I2 (Figs. 2-5) spaced round the periphery of the said sleeve I0 as is clearly shown in the representation of the developed surface of the sleeve (Fig. The grooves I2 I2 serve for the reception of a pin I3 (Figs. 2, 3, l) integral with the upper end member 3. This pin I3 projects into the interior of. the central hole I4 in the end member 3 through which the sleeve slides.

The grooves I2 I2 I2 I2 of the sleeve I0 all communicate with a circular channel I5 (Figs. 2, 5, 6, 7) out near the upper end of the said sleeve,

and this channel I5 thus allows the pin I3 to pass from one groove to another whenthe sleeve) is rotated. 7

Each groove I2 I2 I2 is provided with a stop I6 I6 I6 (Figs. 2, 5, 6) which interrupts the continuity of the groove, but the groove I2 has no stop.

The stops I6 I6 II? are staggered relatively to each other both angularly and longitudinally as is clear from Fig. 5 and these stops come into engagement with the pin I3 when the said pin is in any of the corresponding grooves.

The sleeve I0 is also equipped with retaining or locating grooves consisting of circumferential recesses I1 I1 I1 I1 (Figs. 5 and 8) which are not so deep as the longitudinal grooves- The recess I7 is positioned close to the piston I, while the other recesses I1 I1 I1 are located in line with the corresponding stops I6 I6 I6 respectively (Fig. 5).

The end member 3 also has a retractablestop such as a ball I8 (Figs. 3, '7, 8) lodged in a cavity I 9 of the said end member and pushed by a spring 20; this ball I8 projects into the opening I4 whenever a depression in the sleeve It! comes opposite the said ball. Thus the ball IB projects into the recesses I'l I1 I1 I1 when the said recesses come within the opening I4.

According to another characteristic feature of the invention, the upper end member 3 is constructed of two parts;-a cap 3 and a disc 3 This disc 3 fits freely in the cap 3 and carries the packing ring 5, which is thus interposed ,between the said disc 3 and the cylinder l. Thus, due to the free fitting of the disc 3 in the cap 3 and the elasticity of the joint 5, this disc 3 is of the apparatus is avoided, inspite of any vdefects in workmanship which may occur.

The; disc 3 is'of sucha thickness that, after being'mountedinthe cap 3 it, that is to say the disc3 projects'to a certain extent e relatively to the: said cap-3 I This projecting part of the disc 3 carries the markings R R R R above which moves an index finger 2| (Figs. 2 and 9) located at the top of the sleeve ID. This index-finger 2| has a prolongation 2| 1 which is guided by the projecting part e-of the disc 3.

The positioning, of the markingsR R R R 'is so'chosen thatwhen, for example, the indexfinger 2| coincideswith the marking R the pin I3 is in. engagement with the corresponding groove ,l2

Thelower end member 4 accommodates the suction. tube-system 23 and also the delivery liube-25.

-,- This lower end member 4 (Figs. 2 and 10) is provided with a suction and delivery chamber 30, which passes-through the said member 4 from one side to theothen.

V The chamber 30 has two suction and delivery valves3l, 32, which normally rest on seats 33, 34 cutin the central channel.

This arrangement simplifies the manufacture because the number of elements is reduced; in addition,.the central channel and the seats 33, 34 of the valves 3|, 32 may be producedin a single operation and this materially reduces manufacturing operations, I

The delivery valve 32 is pressed downwards by a spring 35 which bears at its upper end on 'a screw 36, whichalso constitutes aplug, for separating the upper end of the chamber 30 from the interior of the measuring cylinder At the same time, the portion of the chamber 33 situated between the two valves 3|, 32 is in communication with the cylinder I through two auxiliary channels 31 and 33 (Fig. 10).

' Lastly, the portion. of the chamber 33 located below the suction valve 3| communicates with the; suction tube: 23, while the portion of the chamber 30 located above the delivery valve 32 communicates with the delivery tube 25.

During the suction phase (ascending stroke of the piston 'l) the liquid which ascends by the suction tube 23 lifts'the suction valve 3| (Fig. 2) and enters the cylinderl through the auxiliary channels 31, 38 As soon as the suction stroke ceases, the valve 3| closes under the action of its own weight and duringthe delivery stroke, the liquid contained in the cylinder returns into the chamber 30 through the auxiliary channels 31, 38, lifts the delivery valve and flows out through the delivery tube'25. I

The measuring-filler above described is made use of in the following manner:

In the first place, it must be noted that in These transverse displacements of j order to rotate the index-finger 2| and the sleeve In it is necessary that the plunger should be at the bottom of the cylinder (Figs. 6 and 9); in fact, the rotation of the sleeve I0 is prevented by the pin |3 except when the said pin projects into the recess I5 (Fig. 6).

If, for instance, the index-finger 2| is made to coincide with the marking R (Fig. 12), this brings the groove I2 opposite the pin |3 as indicated at I3 in. Fig. 5. The plunger 1 is then raised by means'of the handle II and this movement draws in a. certain amount of liquid through the tube 23 but the plunger is stopped when the abutment or stop I6 in the groove I2 (Fig. 5) meets the pin l3. This movement of the plunger .1 has thus, drawn in; a; volume of liquid Qrrespending to a length of stroke D (Fig. 1-1-)-.

V In order to deliver thisvolume liquid, it is only necessary to push back the plunger Lwhen the liquid is discharged through the. tube 25.

The plunger being again at the bottom of the delivery stroke, the sleeve l0 may berotated to bring any one of the grooves I2 I2 I2 opposite the pin-13, and since the stops inthese grooves are at different distances from the top groove l5 there may be drawn in avolume of liquid corresponding to strokes D D arm of the plungeras indicatedin Figs. 1318.

of the piston 1 and, consequently, to the maxi.-

mum volume of liquid drawn in.

It is possible also to providean indication of the volume measured by marking, on the cylinder volume graduations corresponding to the lengths of the. strokes D D D and D At the end of each suction stroke D D D D 'the ball" |8springs into one of the recesses I1 I1 I7 I1 andthusindicatesto the operator that the plunger T is in a position corresponding to a particular, volume. Furthermore engagementof the ball |8 in one of .the horizontal recesses retains the plunger 1 in position'and thus obviates any risk of accidental discharge of the liquid. 7

Also, the ball l8 rests on the edges of the recess |5 when the plunger 1 is at the end of its delivery stroke and, during the rotation of the sleeve H], the ball l8 indicates, by snapping into one of the grooves I2, that one or other of the grooves 2 has come into position opposite" the pin l3.

It. will be notedalso that all the adjustment of the length of stroke are produced by turning the sleeve IE) on the rod 9 of the plunger 1. This enables one or other of the grooves |2 '-to be brought opposite the pin |3 by the rotation of the said sleeve |0 without thereby involving the lock-nut 42 androtate the apparatus relatively to the bottle 4| to move the tube 25 to the position 25 or 25 and to secure the lock-nut 42 again.

In this'way it is possible to position the discharge tube 25 in the most favourable manner for the reception of the amount of liquid measured. In this way any loss of liquid as a result of incorrect positioning of the discharge tube is avoided.

It will be seen that there is obtained, according to the invention, a measuring-filler by means of which predetermined different volumes of liquid can be measured and in which the transition from a one predetermined volume to another is brought about by a very simple manipulation. This measuring-filler renders it possible also to replenish bottles withaccuracy and without risk of loss.
